A750F 2010-2012 Toyota 4Runner 4.0L AWD/4WD – Remanufactured 5-Speed Automatic Trans

Description

Command 270 horsepower and 278 lb-ft input torque through a 0.72:1 overdrive ratio designed to stabilize transmission sump temperature along extended highway mountain ascents. The Toyota A750F Remanufactured Automatic Transmission fits 2010 to 2012 4Runner 4.0L 4WD platforms. Re-engineered hydraulic circuits hold high line pressure during demanding national park fleet patrol assignments.

Reinforced die-cast A380 aluminum cases resist housing deflection under severe suspension bottoming events. Valve bodies undergo complete hydraulic vacuum checks before installation of Sonnax hard-coat anodized bore sleeves that neutralize pressure bypass. High-energy carbon-metallic clutches run against surface-ground steel reaction discs. Outer housing envelopes include 3/8-inch inverted flare ports, 11.3 quarts WS fluid capacity, and an overall dry mass of 180 lbs.

Key Features of Toyota A750F

Municipal purchasers buy Toyota A750F remanufactured transmission packages to eliminate driveline downtime across park ranger vehicle fleets. Every internal hydraulic circuit receives precision calibration to ensure uninterrupted all-weather traction performance.

• Hardened valve body sleeve inserts prevent cross-bore hydraulic bleeding under high-heat operation
• Segmented friction clutch plates optimize transmission fluid flow across internal friction faces
• Fully balanced lockup torque converter units prevent torsional crankshaft harmonics at highway cruise
• Surface-finished Toyota A750F planet gear assemblies reduce geartrain whine under full payload loads
• High-volume gerotor oil pump designs provide 280 PSI line pressure during high-load low-speed crawling
• Tempered ductile iron planetary gear carriers resist pin elongation under severe shock events
• Deep steel transmission fluid pans feature dual high-gauss magnets for metallic particulate capture

Kinetic Hydraulic Transfer Metrics

System hydraulic line pressure limits regulate between 215 and 285 PSI during wide-open throttle maneuvers. Fluid temperatures balance between 165°F and 185°F under continuous cross-country highway transport cycles. Maximum continuous input torque ratings reach 330 lb-ft at 3,800 RPM in severe commercial duty applications. Internal heat rejection reaches 485 BTU per minute through external oil-to-air cooling radiators. Forward gear reductions include 3.52:1 first, 2.04:1 second, 1.40:1 third, 1.00:1 fourth, and 0.72:1 fifth.

Transfer Case Spline Interface

The unit features a hardened 23-spline output shaft machined to mate flush into four-wheel drive transfer cases. High-strength internal park pawl components withstand 1,550 lb-ft static torque holding force on steep inclines. Dial indicator shaft runout checks measure under 0.0014 inches to prevent front transfer case bearing stress.

Pre-Delivery Checks Service Protocol

Service technicians must perform an electronic TCM shift adapt relearn sequence using diagnostic scan software before regular route deployment. This transmission is not engineered for competition sled pulling events, radical suspension drop brackets, or gross combined vehicle weight ratings exceeding vehicle placards.

• Inspect external oil lines and electrical wiring harness connections every 50 hours
• Extract contaminated fluid and wash internal collection magnets every 30,000 miles
• Perform complete hydraulic fluid changes with approved Toyota WS transmission oil every 12 months

Commercial Warranty Freight Manifest

Purchases include a full 3-Year / 100,000-Mile commercial fleet warranty agreement covering commercial fleet usage. Inside the wooden shipping container rests a remanufactured automatic transmission unit, balanced torque converter, new cooler line sealing washers, and a printed dyno test validation report.
